After driving my GT 55 Coupe for 1,600 miles, I can say without hesitation...no more 911S for me. My GT 55 is the Holy Grail of daily drivers. Question: when I come to a complete stop the ECO Start/Stop system automatically shuts of the engine. Then, even though the vehicle remains stationary and my foot isstill on the brake pedal, after about 1 minute the engine automatically restarts. Is this normal? Is there a way to come to a complete stop and keep the engine off until I take my foot off of the brake pedal? It is very annoying to be stationary and to have the engine automatically restart.

 

Is the A/C on full blast? That might be why.

 

Yes, that's pretty normal. There are many parameters that feed into the start/stop system such as battery SoC, cabin temperature, ambient temperature, battery drain while the engine is off etc. There are electric pumps to keep the oil circulating, so energy is needed to power those. If you accidentally notch the steering wheel, then the power steering uses juice from the battery and it could trigger the engine to restart to avoid the SoC dropping too low. It seems the M177 cannot be turned off for very long, before it needs to restart. Most of us turn off ECO start/stop the moment we start the car. I have no use for it. I find it completely misplaced in a car like this. Feeling and hearing the idling V8 when stopped is part of the experience. It feels jarring when it stops and restarts. However, whenever I drive a 4-banger loaner, I cannot wait for the engine to turn off when I come to a stop. I don't wanna hear that sewing machine clattering while I'm sitting at a stop light, so I leave ECO start/stop on in those kinds of vehicles. These vehicles nowadays also have a 48V mild hybrid system, so the engine can actually stay off for extended periods and restarting it is super smooth.

 

Got her out today from some pops and bangs - need moreeeeeeeee

 

Added spacers:

15f and 18r --- no rubbing on full turns or heavy compressions- Im lowered too.

Side view with spacers- cant really tell from here





AFTER





BEFORE

 

Damn Vic, I want one of these as I was looking a few months ago and I told my wife no more fast cars. This has been my go to as a cruiser, but I do drive the beast alot.

 

Looks great! That looks to me to be about the perfect amount of lowering and spacers for this car, IMO. Well done!

 

Hell ya!!!

I just added the RaceChip Piggy tune and XLR throttle adjuster- really helps in the aggression of the car that should have come from the factory. The RC adds like 70 whp so its not a huge number but its only 700 bucks so the price per hp gain is fair. No DME tunes yet unfortunately.

 

I think Im driving this car too much and wrong!!! LOL Alot of traffic commuting and stop light romps for sure. Thank god its nice and plush.

Look at my mpg

 

this place is so boring --- I posted my car in the Versus section at MPost and got more replies LOL.

Springs settling about 2mm more--- and thats it. Valve Controller coming and exhaust is done son.

 

AMG owners aren't really into modding. That's much more of a BMW thing. Personally for example I'm not a fan of messing up the balance and suspension geometry with aftermarket modifications. You end up operating the dampers out of their intended range and suspension travel, unless you go full coilover with matching springs and dampers. The AMG Ride Control suspension will essentially constantly try to compensate for the lower ride height as it thinks you loaded the car down with passengers and luggage.

But as said earlier, the C192 isn't exactly flying off the shelves and pretty much all sections of the newest models are kinda dead around here. Seems nobody is buying them. Former GT owners are disappointed with the C192 and the heavy E Performance hybrid models aren't getting anybody excited, either. Surprisingly, the new M5 hybrid elephant is selling like hot cakes, so not sure what's attracting BMW owners to it while AMG owners are shunning the hybrid E Performance models.

 

You probably reply more to my posts than anyone

My comment about this place being boring wasnt even about mods but I added what I did to or will do to the car. I am enjoying it so Ill share what I do when I do and continue to drive it and have fun. I have lowered over 50 cars in my life; I understand the geo changes and am ok with what I have and my roads and my driving desires. Others may not and I respect their OEM setups; I just thought this car was excessively high from the factory. It drives the same and feels the same and I got an MB Center to align it withing spec with toe and caster. I dont mind a little bit of negative camber as I turn alot

I know the sampling of forum owners here is really only a microcosm of the true actual owners and thus with the lackluster GT63 sales- I can see why I only chat with a few members here. Ive been with MBworld long before it was IB and have bought quite a few AMGs that had decent forum activity.

Ok back to me posting more pics.

Ironic- I just got an offer at triple net off on an M5 (11% off and choice of two cars)-- the dealer is the Number 1 M dealer and said they are not moving. Who said they are selling well? Their values are so bad that dealers are offering invoice and wholesale auction results are paltry. The price point WAS attractive but knowing M cars like I do (16 of them and 5 M5's in the past) this car is just alot for some of the purists. The Estate is much much more hot but has delayed order package. I wont touch the car as its way too big from a structural standpoint (over 200 inches long) while the GT63 punches way below its weight class with all the chassis tech. But I wont even talk about GT63 values LOL.

 

Hi VIC55, are you using 18mm spacers back and 15 front?

 

Yes indeed

 

As with a lot of cars, its very geographically based. The M5 is selling like hot cakes in Florida. None in stock and zero discounts. Every car incoming is pre-sold and the dealer here are swapping cars from other parts of the US that have slow sales.

 

Thats incredible--- Note to self, get an M5 and sell it in Florida.

Thanks for the input.

 

Big time!!! I just traded my 992.2 for a GT63 (posted the discount in the other thread) and went to drive the M5. Needless to say there were none to drive. they had just received one from Virginia that they dealer swapped for a customer. I was at least able to see it in person. Took one look and told them nope, entirely too big for what I'm looking for. I did drive the refreshed M4 competition. I was surprised how nice it drove but I think I am at least 20 years old to be driving one and too big of a step down for me.

 

Out here, I have over 90 available within 500 miles of my zip---

Im having a buddy run a nationwide query off the BMW NA platform and will report back.

Ill say this about the G8X platform; its amazing and has considerably narrowed the gap chassis wise (damper and spring relations) to that of Porsche. I have had or have 5 different G8X cars and Im no spring chicken but probably drive like one (hence my 8.2mpg with the GT63)

2021 M3 Comp
2022 M3 Comp X
2024 M3 CS
2025 M4 Comp X
2025 M4 CS

The interiors are updated nicely and closer to the quality of the M8 (had two of those)...

My current M4/M3 CS's- drive like race cars, feel very taut and the engine is a super high rev'ing inline 6. The launch like a bat out of hell and are trapping sub 11's on non preps. I love the TCU and Engine tuning on them (level up on the Comps by alot). They do cost more than a normal M3/4 Comp though but are worth the upgrade in my ownership opine.

 

Well said, totally agree.

I have been racing for 28 years. Because of that I look for top notch performance from my cars. To do that I rely on aftermarket components designed by highly qualified engineers to take the car to the next level. I usually purchase 3 or so cars a year and not one is ever left stock. I never want to come out of the store and there are 2 gt63's same color and I don't know which one is mine.
I also sell cars regularly to keep up the rotation ( I am into exotics). I have always sold them quickly even in a down market because people love what's done to it. Not like they can shop other cars because there is just mine. I also typically get well above market most but not all the time. I will actually purchase cars for what they will become vs what they are.

In the end I couldn't imagine driving a stock car but that's me.

 

I appreciate you being the pioneer for mods here LOL...

And while my thread is about the GT63- I like the BMW dialogue too cause its action

 

Were you also on fchat years ago? On a separate note, I went from the GT55 to a GT63 (with the 992.2 in between) and paid less for the 63 than I did the 55.

 

Ha thats incredible--- you must have paid all the money for the 55 and then I saw what you got off the 63... well played. Tell me your thoughts on the 63 throttle? I am so used to a more aggressive pedal or maybe its the TCU and how the 9 speed replies to my commands.


Yeah I used to run Fchat when I had this thing- great car but I always felt it was too much of an event vs just a car I would want to drive all over.

 

That's very accurate. I paid MSRP for the 55, when some dealers were trying to get an ADM. Fast forward to the 63 and I couldn't pass up the huge discount.

In regards to the throttle response, it is definitely not that responsive. Allegedly the computer learns and adjusts to your driving style. My 55 did get a little better after it was broken in. Either that or it was the placebo affect.

This will be one of my daily drivers so I won't push it too hard. I wanted something more luxurious as it's hard to compete with my 750s for performance. I do prefer the GT63 over the 911 for a daily driver.

I had a very similar 458 but had the spider. I go back and forth between Ferrari and Mclaren but lean more towards Mclaren.

 

I installed a RaceChip XLR pedal thingy--- 10 min later I had a better responsive throttle. I heard and basically was always told/learned about the adaptations with benz but even after 8.2mpg for the first few hundreds of miles; I wanted more.

750 is stupid fast.

The GT63 is that sweet spot on the street for sound, quick get up and go's from a dig and decent turning. I like the niche it fits.

 

Completely agree that it's fits the niche. Not many coupes still made that can double as a grand tourer. I think I've owned them all at one point or another. I do miss the S580 coupe and if they start making that car again, I will be first in line.
